How To Remove a Device Tag on a Recoverpoint TDEV

Learned a new tidbit today on removing device tags on EMC VMAX and RecoverPoint. Before you can reclaim a TDEV you must first remove the Device Tag.


In this post we will cover how to remove the device tag, disable write access, un-map, un-bind the device and dissolve the meta on EMC VMAX that is using Recoverpoint


Remove the Device Tag

First get the tag information:

Look for Device Tag(s) in the output

Syntax to un-tag devices


Rerun and now we see it states none

Write_Disable Device

Now that we have removed the Device tag we can write_disable

Un-map the Device

Once we have completed the write disable it is time to unmap the TDEV.

Un-bind the Device

Once the umap process is complete it is time to unbind the TDEV from the thin pool. First get it from the output of the symdev command and look for the Bound Thin Pool Name.

Now that we have the needed information we can unbind the TDEV.

Dissolve the Meta’s

Now that the un-binding has occured we can dissolve the meta’s

That is all there is, the TDEV has been untagged and removed.

      You can use the -f (command file” feature. Create a text file with your commands o change the RP tags. EX: create removerptag.txt file populate with commands and TDEV’s to change.

      set dev 0E1B attribute=NO RCVRPNT_TAG;
      set dev 0E1C attribute=NO RCVRPNT_TAG;
      set dev 0E1D attribute=NO RCVRPNT_TAG;

      Save the file and execute it.

      first check it.
      symconfigure -sid 1234 -f removerptag.txt preview
